Objective To investigate the correlation between thyroid antibody level and carotid atherosclerotic plaque in patients with acute ischemic stroke.Methods Consecutive patients with acute ischemic stroke were enrolled retrospectively.They were divided into a non-plaque group and a plaque group according to the findings of carotid artery color-Doppler ultrasonography.The plaque group was redivided into a stable plaque subgroup and a non-stable plaque subgroup.Chemiluminescence method was used to measure the serum thyroperoxidase antibodies (TPOAb) and thyroglobulin antibodies (TGAb) levels and they were compared.Results A total of 383 patients were enrolled in the study,including 116 (30.3％) did not have plaque and 267 (69.7％) had plaque,68 of them had unstable plaque,and 199 had stable plaque.The level of TGAb in the plaque group was significantly higher than that in the non-plaque group (Z =-4.826,P ＜0.001).Multivariate logistic regression analysis showed that the level of TGAb might be an independent risk factors for carotid plaque (odds ratio 1.007,95％ confidence interval 1.001-1.012;P =0.016).The serum level of TPOAb in the stable plaque group was significantly higher than that in the unstable plaque group (Z =-2.114,P=0.035),but multivariate logistic regression analysis showed that it was not the independent risk factor for unstable plaque (odds ratio 1.001,95％ confidence interval 0.996-1.006;P =0.786).Conclusions The level of serum thyroid antibodies increased in patients with acute ischemic stroke,especially the increased level of TGAb might be associated with the occurrence and development of carotid atherosclerotic plaque,however,it was not associated with the plaque stability.

Objective To investigate the protective mechanism of 7-nitro indazole (7-NI) in neonatal rats with hypoxic-ischemic brain damage. Methods Seventy-two Wistar rats of 7-day-old were randomly divided into the sham-operation、HIBD and 7-NI treated group. The HIBD models were established in 7-NI treated and HIBD groups.7-NI (100 mg/kg) or peanut oil (10 ml/kg) was injected intraperitoneally 0.5 h before hypoxia in 7-NI treated group or HIBD group. NOS,NO,SOD and MDA were examined at different time (1 h、2 h、6 h、8 h). Terminal deoxynucleotidyl transferase mediated dUTP-biotin nick end labeling(TUNEL) method was used to detect neuronal apoptosis. Results NOS and NO level of HIBD group at different time were significantly higher than that of the sham-operation group [NOS:1 h (3.345?0.367)U/mg, 8 h (4.469?0.275) U/mg vs (1.555?0.223) U/mg; NO: 1 h (2.419?0.254) ?mol/g, 8 h (3.556?0.309) ?mol/g vs (0.749?0.135) ?mol/g, P

Objective To investigate the drug induced liver injure(DILI)associated with Chinese herbal medicine and herbal related food supplements.Methods From 1982 to 2005.8.9 consecutive pa- tients were diagnosed as DILI based on their medication history,clinical manifestation,liver function and other laboratory tests.The final retrospection confirmatory diagnosis was made according to the interna- tional scoring system for DILI.Results The 82 DILI patients(28 men,54 females,age ranging from 16 to 81 years old)accounted for 2.2% of hospitalized patients with liver dysfunction.Among those patients with DILI,30.5% was caused by weight reducing drugs or food supplements,12.2% by drugs of derma tology,8.5% by drugs for cardiovascular disease,8.5% by drugs of rheumatology,7.3% by drugs of gynecology,6.1% by drugs for liver disease,6.1% by blood-lipids modulators,3.7% by drugs for thy- roid disease,3.7% by drugs for hyperplasia of mammary glands and 13.4 % by the others.The duration of medication was from 6 clays to 6 months and the incubation period was from 6 days to 3 months.DILI could be classified as acute hepatocellular injury(36.59%),acute cholestasis(39.02%)and mixtures (24.39%).About 10% patients were accompanied by allergic manifestations.All patients recovered rap- idly after stopping the relevant medicine.Conclusion Chinese herbal medicine and herbal related food supplements are a common cause of DILI in China.The awareness and monitoring improving DILI during herbs treatment is a critical issue in daily practice.

Traditional Chinese medicine has multi-component, multi-target, and multi-path action characteristics and complexity, which makes the task of modernizing traditional Chinese medicine arduous, and many medical researchers have made unremitting efforts to this end. The development of systems biology and omics has ushered in an opportunity for the integration of traditional Chinese medicine and modern science. In particular, the characteristics integrity, dynamics, personalization, and interaction with the environment of epigenetics and metabolomics are consistent with function concept of traditional Chinese medicine. The application of popular DNA methylation, histone modifications, miRNA regulation of epigenetic research, and the application of metabolomics in the substance basis, quality control, pharmacodynamic action mechanism in traditional Chinese medicine research are reviewed in this paper. This paper also puts forward the idea that combining the two and innovative application can clarify the scientific connotation of the whole action mechanism of traditional Chinese medicine and the mechanism of multi-component, multi-channel, and multi-target synergistic action at the micro level, and explore a new research model for the scientific connotation of the core thought of traditional Chinese medicine.

Objective To investigate the influence of combined irbesartan/hydrochlomthiazide on morning blood pressure surge(MBPS)and left ventricular mass(LVM) in essential hypertension.Methods After 4-8 weeks' run-in period,if blood pressure wagn't up to the standard,the 120 patients were given irbesartan/hydrochlorothiazide once daily from 150 mg/12.5 mg for 12 months to 300 mg/25mg for another 12 months.MBPS was conducted by arnbuhry blood pressure monitoring(ABPM)and LVM was determined by echocardiography at the end of placebo baseline and 12 months later.Results (1)After treatment the patients with MBPS(+)decreased and patients with MBPS(-) increased.(2)After treatment the extents of MBPS were reduced in MBPS(+)patients[systolic blood pressure(SBP)difference(16.1±1.8)mm Hg(1mm Hg=0.133 kPa)vs(29.4±2.8)mm Hg,diastolic blood pressure(DBP)difference(10.2±2.3)mm Hg vs(21.2±2.2)mm Hg,P<0.01]with little change in MBPS(-)patients[SBP difference(11.2±2.4)mm Hg vs(10.1±1.2)mm Hg,DBP difference(5.9±1.9)mm Hg vs(6.8±3.2)mm Hg]compared with before treatment.(3)LVM indexes of all patients were significantly reduced.Conclusion Irbesartan/hydrochlorothiazide can effectively attenuate the extent of MBPS, and has advantages on reversing left ventricular hypertrophy.

Objective To study the difference in the measurement of the absorbed dose in water between the dosimetry protocols of IAEA TRS-398 and TRS-277 for high-energy electron beams.Methods The differences were compare in absorbed doses from 6 kinds of electron beams among the three methods of using cylindrical chamber,plane-parallel chamber and cross-calibrated plane-parallel chamber which was calibrated in user' s high-energy electron beam according to IAEA TRS-398 and IAEA TRS-277.Results The difference in absorbed doses measured,following the two protocols,was 0.4％-2.3％ for planeparallel chamber,0.6％-2.2％ for cylindrical chamber,and 0.5％-2.0％ for cross-calibrated chamber.The differences in measured absorbed doses between the two dosimetry protocols were slight.Conclusions The methods used to determine absorbed dose to water recommanded by IAEA TRS-398 for high-energy beams are more accurate and more suitable for clinical users to measure compared to the TRS-277.

Objective To determine whether the 12-lead-resting electrocardiogram(ECG) is a predictor of left vertricular(LV) recovery after successful recanalization of chronic total coronary occlusions(CTO).Methods The 12-lead-resting ECG was evaluated for Q-wave areas and parameters of QT dispersion.Impairment of regional wall motion was evaluated by real-time three-dimensional echocardiography(RT-3DE) at baseline and at follow-up.Results The wall motion score index(WMSI) was improved from 1.56?0.31 to 1.12?0.21(P0.05).Conclusion In patients with recanalization of CTO,recovery of regional wall motion is reliably predicted by analysis of the12-lead-resting ECG.
